M. Night Shyamalan

You may not know her name, but 15-year-old actress Nicola Peltz – who stars in the upcoming M. Night Shyamalan fantasy The Last Airbender – could be changing that very soon. Here's why:

 M. Night gives her a rave review."I told the studio I didn't want to make this movie without her," Shyamalan tells PEOPLE. "I said that only once before in my career, and that was when I met Haley [Joel Osment] in the Sixth Sense auditions." They're buds off-camera, too: He came to Peltz's 15th birthday party with his daughters.
